SYDNEY (AP) — India sustained a significant setback ahead of the first cricket test against Australia when young opening batsman Prithvi Shaw was ruled out with a left ankle injury Friday on the third day of a tour match against the Cricket Australia XI.

The 19-year-old Shaw sustained serious ligament damage while attempting a catch on the boundary and, after scans at hospital, was declared unable to play in the first test of the four-test series which begins at Adelaide next Thursday.

Team officials hope he will be fit for the second test at Perth beginning Dec. 14.

Shaw is one of the fast rising stars of India cricket after becoming the youngest India batsman to score a century on test debut during October’s home series against the West Indies.

He was a certainty to open the batting in the first test with either Lokesh Rahul or Murali Vijay and his absence will likely weaken the India team.

Shaw attempted to catch a lofted shot from Max Bryant on the deep mid-wicket boundary. He appeared to have secured the ball but turned his ankle as he tried to stay inside the boundary rope.

He fell to the ground in pain, was assisted from the field and taken to hospital where scans revealed the seriousness of his injury.

“Shaw underwent scans this morning and the reports revealed a lateral ligament injury,” the Board of Control for Cricket in India said in a statement. “Shaw will be unavailable for the first test against Australia in Adelaide. He will undergo an intensive rehabilitation program to hasten the recovery.”

Shaw was on crutches when he returned to the ground later on the third day. He watched his teammates endure a long day in the field as the Cricket Australia XI reached 356-6 at stumps in reply to India’s first innings of 358.
